Rainfall-Runoff Modelling and Flood Hydrology

Module aims

  • To introduce rainfall-runoff concepts and methods and to understand modelling methodologies. This is important as rainfall-runoff models are hydrological tools, extensively used to support flood and water resource design and management and, increasingly, in broader environmental management applications, including water quality and hydro-ecological modelling.
  • To understand flood hydrology: current design, simulation methods, and developments needed to meet new challenges, such as the management of land use and climate change.

Learning outcomes

On successfully completing this course unit, students will be able to: 

  • Become familiar with rainfall-runoff models
  • Carry out rainfall-runoff model-building and performance analysis.
